ments'in Roll-Paper Attachments for Type Writers, of which theyfollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification.

My invention relates to attachments for typewriting machines designed tohold and supply the paper for, the type print ng mechanism, incontinuous rolls, and in which provision is 'made for making manifoldcopies by means of supplemental inking ribbons.

The several features of my invention and the various advantagesresulting from their use conjointly or otherwise will be apparent fromthe following description and claims.

In the drawings, Figure 1 is a side elevation of a typewriting machine,with my improvements applied thereto. Fig. 2 1s a rear elevation of thetypewriter, with the attachment applied; Fig. 3 is a detailed view, inperspective, showing the means for supporting and the tension device forthe paper roll. Fig. 4 is a plan view of the same.

My improvements may be applied to any of the well known constructions oftypewriting machines for visible writing, but the particularconstruction of typewriter with which I have chosen to illustrate myimprovements is the typewriter known as the Underwood, in which theframework of the machine is indicated by 1, the keys by 2, with theimpression. cylinder 0r platen 3 mounted in a carriage 4, which isarranged to be shifted by the operation of the space key to carry thepaper from side to side as the writing progresses. In this form ofmachine, the inking ribbon 5 is mounted on two horizontally disposedspools, one of which is shown at 6 in Fig. 1, which spools aresuitablyjournaled one on one side and the other onthe other side of thecentral portion of the machine, with the ink ribbon carried 'infront ofthe impression cylinder or platen, and between which'and the ribbon thepaper to be written on is passed to receive the impression from the typeselected by the keys operated. For the purpose of advancing th: paperfor line spacing, the impression cylinder 01' platen over which thepaper is carried, is rotatedby means of the line space lever 7, frame.My improved attachment for such a typewriter consists in theconstruction for holding the various rolls of paper from which pivotedat one side of the carriage webs are to be furnished for the printing,

A metal framework is provided for this purpose, comprising vertical sidestandards 8, 9, with cross bars 10 at the top and at the bottom 12.

The lower portion of the frame is sup ported in such a manner as to holdthe same against movement towardor away from the typewriter, but topermit the frame to move freely in the direction of movement of thepaper carriage of the typewriter. This may be accomplished in variousmanners, and, in the present instance, I have shown the bottom 12 asrovided with journal bearings for the spind es of a pair of groovedcarrying wheels 13, 14, by means of which the frame is supported on thetrack 15 to be carried from side to side, with the reciprocal movementof the carriage of the typewriter, and to which the frame is secured,as'will be hereinafter described' At suitable points on the uprights 8,9 of the roll paper frame,

angle plates 16, 16 are secured, which are formed with supports 18 (seeFig. 3-) for r the reception and support of the spindles of the rolls ofpaper, so that the rolls of paper 19, 20, 21 and 22 can be readily andeasily mounted in the frame to rotate freely as the several webs ofpaper are drawn from the rolls. On the end of the paper rolls in whichthe spindles are supported in the plate 16, the rolls are preferablyprovided with disk washers23, to prevent the paper fronicomiug incontact with the standard, while on the opposite end the disks areomitted, and a tension device is provided to bear against the end ofeach roll of paper to maintain proper tension on the paper.

Pivotally mounted on the rod 24, secured parallel with and at the sideof the upright 8 are Z-shaped spring plates 25, one for each roll ofpaper, with the outer section 26 of each plate arranged to bear againstthe end of its respective roll of paper, and with the tension maintainedby coiled springs 27 mounted on the rod 24 above and below the plate andbearing thereon,

mounting the rolls of paper, tm sion ice plates are easily swung awayfrom the rolls H111 shown in Fi s. i3 and The track 15 upon which thepaper roll frame rides is properly rilil )])01"t(5(l at the bottom andrear of the typewriter frame by the braekets29, which brackets aresupported and rigidly secured to the main 't'ra work at 30, 30, byscrews or otherwise; while the roll paper frame is held in. vertieaiposition to be moved. from side to side with the movement of thetypewriter carriage by arms 81, 31, which are pivota'lly secured to thecarriage attachment and at the outer ends are hooked ever studson theroll paper frame at 32, 32.

From the foregoing description, it will be evidentthat the roll paperframe may be readily and easily secured to the typewriting machinewithout interfering with or alterin the machine structure in any way,and also that the rolls of paper may be mounted on, the frame with equalease and convenience.

To load the machine, the paper rolls are first 'mourited in the rollframe as heretofore described, and the paper Webs 91, 92, 93 and 94: arepassed over the guide rods 95, which are mounted on standards 96 on thearms 31 which brace the roll frame in position. The paper webs are thenpassed This is all that is needed, as the lower rolls take care ofthemselves. The device is thus secure from paper falling forward afterthe end has passed through the platen. The tongue will also preventunrolling of the paper on the rolls. 1

The complete detachahility of the attach ment is a very importantfeature. lvlost standard typewriter carriages will serve as a mountingfor it, as it. is back out of the my of working parts. Such alterationsas spacing: the side piece?! and J farther apart for wide carriagesamount to practically no charge. plurality of rolls could be adapted tmany kinds of machines and in the use of words typewriling machine inthis specification, kindred and allied machinery .is intended to hecovered as well.

Having thus described my invention, what I claiinas new and desire tosecure by Letters Patent, is

1. In a manifolding attaclnnent for typewriting machines, a frame forcarrying a number of rolls of paper comprising upright bars, hearingplates on said bars for the rolls of paper, upright rods parallel to thebars, and tension devices for the rolls of paper mounted on the rods andbetween them and the bars.

2. In a manifoldinp; attachment. for type writing machines, a frame forcarrying a number of rolls of paper comprising; upright bars, hearingplates on said bars for the rolls of paper, upright rods parallel to thebars, and tension devices for the rolls of paper mounted on the rods andbearing on the bars:

3. In a manifolding attachment for typewriting machines, a frame forcarrying a number of rolls of paper comprising upright here, bearingplates on said bars for the rolls of paper, upright rods parallel to thebars and spring plates having fiat per tions for contacting with therolls, and

mounted on the. rods and extending" between them and the bars so as tobear on the bars.

4:. In a manifolding attachment for typewriting machines, a frame forcarrying a number of rolls of paper comprising upright; bars, bearingplates on said bars for th rolls of paper, upright reds parallel to thebars, and tension devices for the rolls of paper mounted. on the rodsand between them and the bars, said frame having; a cross bar at the topand tension means for the sl ects of paper after they leave the rolls.
